Answer :

Final answer:

In reference to the AWS B2.1/B2.1M:2014 welder qualification, a welder tested in the 6-G position on an SA 106B pipe would be qualified to weld a 2" 300# ANSI schedule 80 flange to a 2" SA 106B nozzle neck.

Explanation:

According to AWS B2.1/B2.1M:2014, for a welder who has been tested in the 6-G position with an E-7018 F-4 electrode, on 6" sch 160 (.718" nom) SA 106B pipe, this welder would be qualified to weld a 2" 300# ANSI schedule 80 bore flange to a 2" schedule 80 SA 106 B nozzle neck. The process used to qualify a welder correlates to the ability to perform similar welds.

This is because, in practical welding scenarios, the testing done has more to do with the welder's skills than the specifics of the materials being bonded. Essentially, if a welder is proficient enough to pass a test in the 6-G position on a certain size and type of pipe, they should be able to apply similar skills to welding a slightly different type and size of pipe.
